LSRAEL United States Patent O 3,505,681 HOOD FOR A GARMENT USED IN CONTROLLED ENVIRONMENT ROOMS Milton W. Israel, St. Louis, Mo., assignor to Angelica Corporation, St. Louis, Mo., a corporation of Missouri Filed Sept. 20, 1968, Ser. No. 761,031 Int. Cl. A41d 13/00, 13/02 U.S. Cl. 2--84 5 Claims ABSTRACT OF THE DISCLOSURE BRIEF DESCRIPTION OF THE INVENTION Garments such as Coveralls or smocks for use in controlled-environment rooms are made with an integral hood so that maximum coverage of the wearers body is realized. These garments are made entirely from fabric in which the pores through which contaminating particulates might pass are kept to a minimum. The purpose of such garments is to provide nearly complete coverage of the wearer with a garment that filters the transfer of such contaminating particulates from the wearer to the room, such as a hospital clean room. Such garments may be made from a continuous-filament high-tenacity polyester having 220 denier yarn in both directions, for example.

This invention maintains such a clean room garment construction, but incorporates individual panels in the hood of the garment adjacent the ears of the wearer. These individual panels are also of a continuous filament synthetic fabric but are knitted to provide a softer fabric. These paniel inserts, while too porous for the rest of the garment, are small and do not transfer significant amounts of contaminating particles, Yet, they overcome the noise from reverberations of the hard and non-porous fabric used for the main portions of the garment.

BRIEF DESCRIPTION OF THE DRAWING FIGURE l is a front isometric view of the clean room hood with dotted lines showing its integral formation in a clean room coverall.

FIGURE 2 is a right side elevation view of the hood lying flat.

FIGURE 3 is a left side elevation View of the hood lying fiat.

FIGURE 4 is an enlarged fragmentary view in section taken along line 4 4 of FIGURE 2.

FIGURE 5 is an enlarged fragmentary view in section taken along the line 5-5 of FIGURE 2.

The hood is shown formed integrally with a clean room garment, such as a coverall or a smock. Two panels 11 and 12 made from a continuous-filament high-tenacity rice polyester or equivalent fabric are joined together at a seam 13 down the back of the hood and across its top. The fabric for these panels 11 and 12 may be any other suitable fabric used for conventional hospital clean room garments. Such fabrics are substantially non-porous so that contaminating particulates will be filtered rather than pass` through the fabric.

For this hood, there are two special panels 14 and 15 incorporated into the hood 10 at locations adjacent the ears of the wearer. These panels 14 and 15 are each approximately 21/2 inches high and 5 inches wide so that they will be next to the ears even though the hood moves somewhat forwardly or backwardly and to accommodate different head sizes. The panels 14 and 15 are of knitted fabric to be soft and eliminate noise and reverberatons caused by denser and harder fabrics rubbing and moving about the ears.

The panels 14 and 15 are joined along stitch lines 16 and 17 to openings formed in the panels 11 and 12 and along stitch lines 18 and 19 to seams 20 and 21 formed in the panels 11 and 12. The front edges 20 and 21 of the insert panels 14 and 15 are seamed to correspond with seams 22 and 23 along the forward edges of the panels 11 and 12.

Thus, this hood provides almost complete coverage of the head portion of the body while providing inserts that: eliminate noises and reverberations at the ears of the wearer.

Various changes and modifications may be made within this invention as will be readily apparent to those skilled in the art. Such changes and modifications are within the scope and teaching of this invention as defined by the claims appended hereto.

What is claimed is:

1. In a fabric garment, a hood construction comprising main fabric portions adapted to cover a human head and insert panels joined to said main fabric portions, said insert panels being positioned to be located opposite the ears of the human head, said fabric portions being of low porosity material to filter passage of contaminating particulates, said insert panels being of relatively more highly porous fabrics.

2. The hood of claim 1 wherein said insert panels are of continuous filament knit fabric.

3. The hood of claim 2 wherein said insert panels are of synethetic fabric.

4. The hood of claim 2 wherein said main fabric portions is of continuous-filament high-tenacity polyester material.

5. The hood of claim 1 wherein said insert panels are about 21/2 inches high and 3 to 6 inches wide.
